Title: Color adjustment device
Inventor: UEDA MASASHI
IPC: G09G5/00
Filed: 1995-12-27
Abstract: PROBLEM TO BE SOLVED: To ease color adjustment by allowing to instantaneously lock at the same position of different images without being accompanied by a shift of the viewpoint. SOLUTION: The same image data before and after color adjustment is alternately displayed on the same position of a CRT display device with intervals of one second by installing the screen change and interrupt processing at the step of color adjustment processing (S140). Therefore the operator exactly confirms the condition of color adjustment without shifting his/her viewpoint. In addition, the screen is switched at one moment and accordingly the color difference between two images can be conformed at once, allowing more exact confirmation of the conditions of adjustment. And since the display region of the CRT display device is not divided into display images concurrently, the entire display region of the CRT display device can be utilized for each image, and high-resolution images are exactly displayed, allowing more exact conformation of conditions of adjustment.

IPC: H04N5/78
Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To provide an effective atmosphere to a reproduced moving picture without recording a shutter noise at reproduction of the moving picture by storing a count of a tape count means to a storage means in a timing when a still image is recorded by a still camera. SOLUTION: A control circuit 10 detects whether or not a reproduction stop command signal is received from a video camera operation section 6b of an operation section 6. The control circuit 10 provides the reproduction stop command signal for a video signal processing circuit 13 of a video camera section 3 and a tape drive mechanism 15 when the control circuit 10 receives the reproduction stop command signal from the operation section 6b to release the reproduction state of the video camera section 3. When the control circuit 10 does not receive the reproduction stop command signal from the operation section 6b, the control circuit 10 keeps the video camera section 3 to the reproduction state.  Then the control circuit stops the reproduced moving picture by the video camera section 3 for a prescribed time in a timing when a still camera section 5 picks up a still image in the case of reproduction. The timing of the still image pickup is recognized through the indication of denoting a fact of the still image and an effective atmosphere is provided to the reproduced moving picture.

Filed: 1989-12-27
Abstract: PURPOSE:To make a front protective time (n) times of a conventional system and to make a frame synchronizing circuit immune to burst error by controlling a protective circuit so that front protection can be finished when pattern discordance is detected continuously certain number of times at the (n) times period position of a frame pulse position in an output from a frame counter. CONSTITUTION:When the pattern discordance is continuously detected at the (n) times period position of the frame pulse position, the front protection is finished and a rear protective state is started by turning a set/reset flip-flop 12 of a protective circuit 14 to a set state. Therefore, while maintaining the front protective time (n) times of the conventional time, an operation can be moved to a synchronizing step-out state with more than a conventionally same average random transmission line error rate. Thus, even when a frame period is short, the frame synchronizing circuit can be made immune to the burst error.
